Provided is a display control device that can, even with a self-emitting display, minimize power consumption and dramatically increase the battery life time of information device. The display control device includes: a phase adjustment circuit that adjusts a phase difference between input image data including a vertical blanking period and memory image data read from a frame buffer, by adjusting the number of vertical blanking lines on the basis of a difference between the number of vertical lines related to the input image data and the number of vertical lines related to phase adjusted image data in which the number of vertical blanking lines related to the memory image data is adjusted, and generating the phase adjusted image data; a selector that outputs the phase adjusted image data to the display as output image data in the period lasting until image display under PSR terminates; and a vertical line number calculation circuit that outputs a vertical line number signal related to the number of vertical lines related to output image data to the display until when a head of a frame of the output image data is output.
